The ".1" upgrade is genuinely significant - more so than the numeric designation might suggest. Taking my MA-1s from 3 -> 3.1, I was impressed with the improved quietude and audible reduction of distortion, which cashed out as superior intonation, poise, and heightened intelligibility across the frequency range. You say to yourself 'well, I figure it will be better' but it is hard to conceptualize that 'betterness' until you actually hear the differences in your own system - of course by then you're beyond concepts. If you own an amp under 3.0, I suspect the upgrade improvement is exponential.
